A nine hours' bus ride on exposed winding roads took us to the village of Uttarey, the starting point of our two-weeks' trek. From Uttarey (1920 m) we walked through natural rainforest until we reached the top of the Singalila Range - the border range to Nepal - at Chewa Bhanjang (3140m). The ascent of Singalila Peak (3685m) can be recommended to improve acclimatisation. For five days we threaded our way up and over the highest reaches of the Singalila Range traversing some 4000m passes (4600m maximum) until to Gomathang at 3800m. During this walk we had excellent views of the Nepalese Khumbu Himal, Kabru, Kangchenjunga and Pandim up to the border mountains of Tibet and Bhutan. Via Tikipchu we finally reached the beautiful campsite at Dzongri where we joined the main trekking route from Yuksam to Goecha La.
